Muir's Sage problems — and how to fix them
Muir's Sage (Salvia muirii) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Dieback from waterlogging
Salvia muirii is highly sensitive to wet roots; waterlogged or poorly drained soil quickly causes stem dieback and root rot, particularly in winter — raised planting is recommended in heavy soils.
Legginess with age
Plants become woody and open-centred after 3–4 years; prune lightly after flowering each year to maintain compact, bushy habit and delay the need for replacement.
